Sun UltraSparc IIIi Solaris 5.10 emulation

I have an old Sun Blade 1500, with a Ultrasparc IIIi 1.5 GHz, 2GB ECC RAM. SunOS 5.10, ufs filesystem. The hardware (MB, HDD and video card) is failing on me and I'm searching for a way to emulate it on x86 hardware. I have a DD raw copy of the HDD that I tried to mount it on Linux but i'm getting: disk cannot be accessed. I read about emulating it with qemu but I don't have much experience with Sun/Solaris and Linux environments. Has anyone tried and succeeded emulating a system like this? Thank you
